    Wheeler]

  - Switch to pg_ctl in tests for more reliable (and faster!) Postgres

    properly cleaned up on shutdown even if Postgres is down. [David Wheeler]

  - Tests now properly report the reasons for failed bucardo commands. [David
    Wheeler]

  - Fixed issue with missing database handles when a KID shuts down. [David
    Wheeler]

  - Remove the customselect parameter. Use the customcols command, instead.
    [David Wheeler]

  - Remove the do_listen parameter, which was just another name for ping.

  - Rename the 'ping' parameter to 'autokick', to better describe what it does
    and to prevent confusion with the 'ping' command, which does something
    totally different. [David Wheeler]

  - Rename standard_conflict to conflict_strategy. [David Wheeler]

  - Move conflict_strategy from add/update table to add/update sync. [David Wheeler]

  - Fix issue that prevented the VAC process from shutting down immediately on
    'stop'. [David Wheeler]

  - Fix failure to restart after database disconnections.

  - Add 'remove sequence' [David Wheeler]

  - Rename most --debug* options to --log-*:
      + --debugdir is now --log-destination
      + --debugfile is deprecated; use '--log-destination none' to disable all logging
      + --debugsyslog is deprecated; use --log-destination syslog'
      + Allow logging to stderr or stdout via --log-destination
      + --log-destination may be specified multiple times for multiple logs
      + --debugfilesep is now --log-separate
      + --debugname is now --log-extension
      + --cleandebugs is now --log-clean
    [David Wheeler]

  - Eliminated 'Use of "goto" to jump into a construct has been deprecated'
    warnings on Perl 5.12 and higher.

  - Removed the 'trigrules' attribute for customcodes. Callers should 
    (carefully!) change session_replication_role themselves. [GSM]

  • Remove the unused t/bucardo.test.data file [GSM]

  • Fix sequence replication by setting is_called properly on the targets [GSM, thanks to Selena Deckelmann for discovering this]
  • Respect server_side_prepares db setting in validate_sync. Previously, this function would fail if validating more than one table at a time and the database was set as server_side_prepares off [GSM]
  • Make sure we cast rowid* to text within the bucardo_add_delta-called functions, for picky versions of Postgres. [GSM]

Bucardo version 4.1.1, released September 24, 2009

  • Fix case where Bucardo was too eager to lock tables post serialization failures. Since we can't really do this automatically and safely, remove the code in question for now. [GSM, hat tip to Selena Deckelmann]

Bucardo version 4.1.0, released September 24, 2009

  • Fix problem with possible function name collision when the names of the combined columns in the primary key is greater than NAMEDATALEN, which we'll assume is 63. [GSM]
  • Add "bucardo_ctl inspect table" to show all dependencies, as well as cross referencing against herds the table is in [GSM]
  • Fix an error when validate_sync tries to recreate an existing trigger; occurred when a fullcopy sync was set to ping=true [GSM]

  • Add new boolean column to the "db" table named "server_side_prepares", which is true by default. If off, Bucardo will not use server-side prepared statements, and thus can be used in PgBouncer's transaction mode. [GSM, idea by Andrew Spencer]
  • During pushdelta, break large number of rows for a single table until multiple DELETE and COPY calls, to help debugging, to allow for a progress indicator both at the Bucardo and Postgres levels, and to prevent crashes seen on older versions of Postgres when very large IN() lists are used. [GSM]
  • When using "bucardo_ctl add all tables", ignore any tables inside schemas starting with 'bucardo' [GSM]
  • Allow --verbose flag for list syncs to show linked tables [GSM]
  • Allow --verbose flag for list tables to show linked herds and syncs [GSM]
  • Change rebuild_index to a smallint: a 1 only runs it with a fullcopy. If you really want to use it otherwise, set it to 2 [GSM]

  • Allow ping to be specified for new tables added via "add sync" [GSM]

Version 4.0.2, released September 16, 2009

  • Add the name of the database to the install choices, as some systems have mismatched names (BSD's 'pgsql' user) [Vilem Kebrt]
  • Clear out stale q entries on startup, created when a kid was hit with a kill -9. This was causing Bucardo to think the q slot was still active. [GSM]
  • Fix cases where we were not quoting the UNLISTEN names [GSM]
  • Remove duplicate PID numbers from log [GSM]
  • Prohibit syncs from having names reserved for synctypes. [GSM]

  • Allow "foo*", "*foo", and "*foo*" wildcard format in bucardo_ctl when specifying syncs, e.g. bucardo_ctl kick ABC* [GSM]
  • Allow special cases for bucardo_ctl kick: "all [synctype] [active]" [GSM]
  • Allow filtering of 'bucardo_ctl list syncs' by synctype [GSM]
  • Allow 'bucardo_ctl add sync tables=...' to work with schema.table format [GSM]

New features:

  • Add support for multi-column primary keys. Thanks to Backcountry.com. [GSM]
  • Add new 'onetimecopy' attribute to sync table, to allow recreation on demand of pushdelta tables on slaves via COPY. [GSM]
  • Support for replication after TRUNCATE. This will only work on Postgres version 8.4 and higher, and only pushdelta syncs. [GSM]
  • Add log_conflict_details to allow logging of conflict information to a separate file. [Adam Wendt]
  • Add 'maxkicks' and 'lifetime' to syncs to force restart of controller and kids after a certain number of kicks or time. [Josh Tolley] Thanks to Backcountry.com.
  • Add the bucardo_custom_trigger table, which allows tight control of exactly what items in a table will be replicated. [Ben Allen]
  • Add the bucardo_rate table to track exactly how long replication takes on a per-sync and per-table basis. [GSM]
  • Add more bucardo_ctl actions: install, reload, validate, restart, update [GSM]
  • Allow adding of all tables in a database at once via bucardo_ctl [GSM]
  • Add in bucardo_compress_delta function, to remove duplicate rows from the bucardo_delta table. [GSM]

Enhancements:

  • Remove 'Moose' dependency. [GSM]
  • Remove disable_triggers and disable_rules from the sync table. We simply choose pg_class or replica based on the version of the database in question. [GSM]

  • Add more tests and improve existing ones. [Josh Tolley]
  • Force READ WRITE mode so Bucardo works on read only databases. [GSM]
  • Make the audit_pid table more useful. Use sequences instead of PIDs to find children. Allow for the audit_pid table to be toggled off. [GSM]
  • Remove the debugstderr and debugstdout options, as they never worked correctly anyway. [GSM]
  • When truncating during fullcopy, fallback to delete if it fails. [GSM]
  • On startup, all syncs that may have trigger-based notifies are initially kicked. [GSM]
  • MCP listens for pings during table validations. [GSM]
  • Have master_q use a trigger, not multiple rules. Remove the need for a separate create_child_q() function. [GSM]
  • Default for log_showtime is now 'scalar localtime' rather than epoch seconds. [GSM]
  • No longer require a reason for the "stop" action. [GSM]
  • Add INSTALL_BUCARDODIR for quick and dirty 'make install' [GSM]

  • Fix failure to disable/enable triggers when using pg_class and table and schema are words changed by quote_ident. [Ben Allen]
  • Tolerate incompatibility in DEFAULT of negative numbers between Postgres 8.2 and 8.3. [Jon Jensen]
  • Do better checking of bucardo_ctl executable when MCP is restarting. [Ben Allen]
  • Change timestamp to timestamptz where needed inside Bucardo.pm [Yan Farmawan]
  • Put schema in db_getconn calls [Alex Bahlai]
  • Record the proper PID for the MCP in the pid file [Goran Gugic]
